Is there a way to get the the command line to focus when using shortcut commands? (currently using OSX if that matters) I am coming from ACAD and to be able to just type in commands, including command options such as the first point, second point, radius, etc without having to touch the mouse would be great.

I'm a noob , I see now. Also focus the option tool bar with Ctrl-Space. I guess it'll take a bit to get used to, it's just a bit awkward until then, plus once I start to understand the UI and the design reasons/choices I'll be rocking.
